I removed the Gujarati-A samples from the previous set of runs and ran admixture on the resulting dataset.
Nothing new pops out except that the Siberian component splits into Turkic/Tungusic and Nganasan components at K=12.
The admixture results are in a spreadsheet as usual.
K=11 & 12 have the lowest errors.
At K=13, Chenchu split off as their own cluster.
